Hi there, I am putting the finishing touches on my first chicken coop and need advice on making it secure. 1) I have chosen to use hardware cloth for the base of the coop. Someone told me to dig a small trench and bury it, but won't it just rust? 2) I am using a chain link dog run for a chicken run. I picked up some free bricks and thought I'd line the perimiter with them. Will this be effective in deterring predators from digging? I would appreciate any advice and insight. Thanks a bunch!
